The principle of the PCBA test jig is very simple. It connects the pads or test points on the PCB board through metal probes. When the PCB board is powered on, the typical values such as the voltage value and current value of the test circuit are obtained, so as to observe the tested circuit. Whether the circuit is turned on normally.

The production of PCBA test racks is customized, and it is determined according to the size of the PCB board to be tested, the location of the test point, and the value to be tested. Acrylic, plastic, metal probes, display screens, wires and simple PCB circuit boards are mainly used to complete the whole production. .

The PCBA test stand is widely used in the entire PCBA processing and production process. It is mainly used to test the PCBA board after the SMT patch and DIP plug-in are completed. Among them, the ICT test is mainly used, that is, the electrical conductivity of the circuit board is tested through the test point. performance, so as to determine whether the entire PCB board is soldered successfully. The PCBA test stand is the main tool used to assist in completing this test.
